20.500.12556/DiRROS-24536 Concentric needle electromyography findings in patients with ulnar neuropathy at the elbow In ulnar neuropathy at the elbow (UNE), the degree of neuropathic changes, the sensitivity of needle electromyography (EMG) in individual ulnar muscles, and the utility of individual EMG parameters are controversial. I compared qualitative needle EMG findings in two ulnar-innervated hands muscles and two ulnar-innervated forearm muscles in a group of previously reported UNE patients. Altogether, 170 UNE patients (175 arms) were studied. I found spontaneous denervation activity (SDA) most frequently in the first dorsal interosseus (FDI) (62%) and neuropathic changes in the abductor digiti minimi (ADM) muscle (88%). In the forearm muscles, SDA was more common (29% vs. 20%; p = 0.02), and neuropathic changes were similar in the flexor carpi ulnaris (FCU) and the flexor digitorum profundus (FDP) muscles. SDA and neuropathic changes were more common in the ulnar hand (88% and 77%) than in the ulnar forearm muscles (71% and 68%). Needle EMG is sensitive to diagnose UNE. For the detection of SDA FDI and neuropathic changes, ADM is the best muscle. Ulnar forearm muscles are less useful than ulnar hand muscles for UNE diagnosis. electrodiagnostics needle electromyography neuropathic changes peripheral neuropathy spontaneous denervation activity ulnar neuropathy true false true Angleški jezik Ni določen Neznano 2025-12-04 13:28:57 2025-12-04 13:28:57 2025-12-06 03:41:05 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 26. 5. 2025; str. 666-673 iss. 4 Vol. 5 Dec. 2024 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 61 2673-4087 10.3390/neurosci5040047 237132291 RAZ_Podnar_Simon_2024.pdf RAZ_Podnar_Simon_2024.pdf 1 934A321DCC36BA58F190FD83335189DB da03247b6c1f9cd42cb9645da4c1c9dc13881e4adcf5c26a036d963b91588926 e91a965d-d10c-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=36590 https://www.mdpi.com/2673-4087/5/4/47 1 cfc56b9c-d10c-11f0-94a7-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=36589 Univerzitetni klinični center Ljubljana 0 0 0
